Sailing By features a specially chosen selection of material broadcast on Seascapes, RTÉ Radio 1’s dedicated maritime programme. Originally developed and presented by Tom MacSweeney, who retired in 2009, the helm has passed on to Marcus Connaughton who now presents and produces the weekly programme. Essays include:

 Sailor and explorer Paddy Barry’s circumnavigation of the island of Ireland

 W.M. Nixon on Ireland’s sailing tradition

 Pete Hogan on building his own boat and sailing it down the coast of California, through the Panama Canal and across the Atlantic to Ireland
